Minerals, Rocks Rock Forming Processes

Clastic Sedimentary Rocks are those that are composed of fragments of other rocks (igneous, metamorphic, sedimentary). In some cases the prevalent color of the rock may be used instead of a mineral name, particularly if such color is due to a certain mineral.

How Rocks Change Introduction Does it seem to you that rocks never change? For example, if you find a chunk of granite today, can you expect that it will still be granite at the end of your lifetime? All rocks, in fact, change slowly from one type to another, again and again. The changes form a cycle, called the rock cycle. The way rocks
